Robby is the diminutive of Roberto.
I was born in 1967 and just when I was a child, maybe 3-4 years old, I
started to play my firsts 45rpm discs on my "disc-eater", so I was
impressed of how magic was that playback system only looking the disc
turning around! At the same time I was very interested of all about
electronic, then, transistors, vacuum tubes ,resistor and capacitor was
my firsts true toys. During all the years many was the steps about the
various interests, all in the field of analog electronic,
Radio-frequency telecommunications, hi-end audio and other... but the
true dream was the cut of vinyl discs: when I was children, I did try to
cut with an old player ceramic cartridges on homemade wax discs..
naturally without success ...
In 1993 I did put my hands on a very old American Presto 6N lathe,
equipped with Presto 1-D mono cutter and the original like-new full
tubes A-93 amplifier: really nice but far from a true high-fidelity
system and, after many many unsuccessful tests the first good lacquer
was cut.
With the incoming of internet and the constant help of great local
electronic technician friends, many secrets and things about the cutting
was discovered and an old destroyed cutterhead Neumann SX68 was
self-badly-repaired and adapted to the lathe... so here started the true
adventure with so much technical difficulties, to obtain the maximum
possible and to really learn the physical limits of the system.

Thanks to the constant everyday research, big
nerves, many many nights spent to know and study and the most
important thing: the true passion, I and my technician/audiophile
friends, decided to rebuild and remake all the original
circuitry taken by the original Neumann diagrams with selected
new components.
We obtained for the VG66 pre-amplifier like feedback electronic
earth, because is all FET and transistors made, highly accurate
in signal symmetry with an high output and easy to manage
without so much critical points and, for the RIAA encoder, we
adopted a self made vacuum tube push-pull amplifier with
selected original Telefunken, Philips "special quality" and
Siemens tube, with PASSIVE RIAA...instead of the original
SE66ic.

This solution assures an amazing sound quality and precision in
the delicate RIAA encoding, with great warmth in the sound. I
have 4 of these preamp systems and various power electronics,
the most with Mullard power tubes capable of a very beautiful
end powerful wideband sound on the vinyl, thanks also to the
Neumann cutterheads.
I learned well how to repair in all last years. And because I
know well the limits of this system there is not a big fear to
burn, because I can remade myself the cutterheads.The volume
level on the discs can be keep the higher physically possible
with the Neumann cutterhead repaired here with the latest wire
technology adopted which has the higher insulation heat
resistance possible and a relatively low mass for the better
response in the hi-treble end..

The cutters here are completely
rebuild by me, and because I studied deeply the structure of Neumann
heads, I'm capable to give new life to your old SX68 - SX74. This all
means a great responsibility, because a similar work is extremely
delicate and will affect the performances of your vinyl cuttings. I
suggest however to re-setting the feedback level of your new rewound
cutter when you'll put for the first time on the lathe after repair,
because some difference by the previous old wires will be unavoidable
even if I follow the original characteristics made by Neumann 30 years
ago.
I and my collaborators are sure to give you the best service we can do,
because we didn't started this all strictly for business, but for the
passion we had (and have) for this field, because the vinyl disc cutting
is a true art, unrivaled by any other digital media... with all his
analogue and physical limits, and this true science cannot be forgot
only because the latest audio technology makes all easy with mp3 or
other.. I sincerely believe at this all, and want to try to fully work
with the maximum professionalism and service for who really wants to
continue with this magic system
